Seal, in particular electromagnetic seal

Abstract

An electromagnetic seal consists essentially of an oblong metal plate with two bends along two parallel longitudinal bending axes (D1, D2) defining on the plate two lateral flanges (34, 35) inclined relative to a central panel (36), and an central oblong opening (29) which has a width (a) slightly less than the distance (b) between the bending axes so that parts of the central panel situated on the longitudinal edges of the central oblong opening, separated before bending by cut-outs on the transverse edges of the opening and between the bending axes and the central oblong opening, are adapted to form oblique extensions of said lateral flanges in the region of the central oblong opening.

We claim: 
     
       1. Seal for attaching a first member such as an oblong electrical connector housing providing protection against electromagnetic interference having a first bearing surface at an edge thereof to a second member such as an electromagnetic interference protection shield including an opening adapted to receive said first member and retain it by virtue of engagement with said first bearing surface, the periphery of said second member about said opening forming a second bearing surface, said seal comprising an oblong metal plate folded along two longitudinal folding axes thus defining on said oblong plate two lateral flanges and a central panel, said lateral flanges being inclined relative to a central panel with an inclination enabling opposed outer edges of said lateral flanges to bear against said second bearing surface on application of a force to the oblong metal plate tending to return said oblong metal plate to its shape before bending, said metal plate further comprising a central oblong opening having transverse edges being sized and adapted to receive said first member and said central oblong opening having a width slightly less than the distance between said folding axes so that parts of the central panel situated between the transverse edges of the central oblong opening the oblong metal plate and separated by cutouts, form extensions of said lateral flanges in the region of the central oblong opening in the oblong metal plate with the same inclination as the lateral flanges and bear against said first bearing surface on application of said force.
